Ladder Climber Blueprint System for Unreal Engine
A blueprint-based solution for implementing ladder climbing mechanics in UE projects.
This video showcases the LadderClimber System integrated with Unreal Engine's GameAnimationSample (GAS). The system provides ladder-specific animations and logic that seamlessly transitions with MotionMatching-driven locomotion states.
Note:
The LadderClimber package does not include GAS implementations.
GAS integration requires custom setup on your project.
System Overview
This system provides 20+ ladder animations with optimized animation curves and precise state transition timing, ensuring smooth climbing interactions. It seamlessly integrates with Unreal Engine's GameAnimationSample workflows and supports network replication for multiplayer synchronization. Built using Animation Layer Interfaces, it preserves existing animation logic while adding ladder functionality without conflicts.
The BP_LadderDetector component automatically detects climbable ladder meshes or allows manual customization of ladder dimensions. A demo map (Maps/LadderClimberDemoMap) is included to demonstrate core features and provide step-by-step integration guidance, with detailed annotations in blueprint assets.
Key Features
20+ Ladder Animations - Diverse climbing motions with optimized animation curves and frame-accurate state transitions.
GameAnimationSample Compatibility - Smooth transitions between standard locomotion animations and ladder-specific actions.
Multiplayer Support - Network-replicated climbing logic for synchronized behavior in multiplayer environments.
BP_LadderClimber Component - Handles core climbing mechanics and can be easily integrated into existing character blueprints.
BP_LadderDetector - Automatically detects ladder meshes or allows manual setup for non-detectable assets.
Animation Layer Integration - Implements climbing logic via ALI_LadderClimber without modifying existing AnimBP graphs.
Plug-and-Play Setup - Add components and connect interfaces to embed functionality with minimal setup.
Demo Map - Pre-built example map (Maps/LadderClimberDemoMap) showcasing implementation best practices.
Implementation Steps
Add Components to Character
Attach BP_LadderClimber to your character blueprint.
Implement the ALI_LadderClimber interface in your AnimBP.
Setup Ladder Detection
Place BP_LadderDetector actors in your level.
Adjust detector position/scale to cover target ladder meshes (auto-detection) or manually define dimensions.
Verify Functionality
Test transitions between locomotion and climbing states.
Review blueprint comments and demo map for advanced configuration.
Required Plugin:
Unreal Engine's Motion Warping Plugin must be enabled in your project.(Edit > Plugins > Animation > Motion Warping)
